Skudderbutt, often called tire mark, is a term used to characterize a blemish left behind by a vehicle during skidding. Skudder bottoms are noticeable on streets in the midst of icy situations, like heavy rain or snow. These marks serve as warnings to likely skidding or lack of traction and should be approached with caution. Motorists are recommended to lower their speed and keep up a safe distance from skudder bottoms to prevent any potential crashes. Stay safe on the roads!
